Knowledge Check: The Rock Cycle

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various stages: igneous, sedimentary, and metamorphic.

Front

What are igneous rocks?

Back

Igneous rocks are formed from the cooling and solidification of magma or lava.

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of sediments, which can include minerals, organic matter, and fossils.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed when existing rocks are changed by heat, pressure, or chemically active fluids.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals through contact with the Earth's atmosphere, water, and biological organisms.

Front

What is sediment?

Back

Sediment is small particles of rock, minerals, and organic material that are transported and deposited by wind, water, or ice.

Front

What is melting in the rock cycle?

Back

Melting is the process where solid rock turns into magma due to high temperatures.

Front

What is cooling/crystallization?

Back

Cooling/crystallization is the process where magma or lava cools and solidifies to form igneous rocks.

Front

What is the role of pressure in the formation of metamorphic rocks?

Back

Pressure can cause existing rocks to change their structure and mineral composition, leading to the formation of metamorphic rocks.
